Stranded astronauts Barry 'Butch' Wilmore and Sunita 'Suni' Williams are nearing their return date, and have now revealed the hardest factor of their nine-month stay aboard the International Space Station (ISS).

The two Nasa astronauts who have been 'stuck' on the International Space Station since last year are now a few weeks away from returning to Earth and to their friends, families and loved ones. Butch Wilmore and Suni Williams were unable to return home on their spacecraft due to a number of issues.

NASA astronauts Suni Williams and Butch Wilmore have said they were unaware of any offer by Elon Musk to bring them back to Earth early, in a press conference from the International Space Station (ISS) on Tuesday.
